GRAIN-SHOCKING- ATTACHMENT FOR HARVESTING-MACHIN ES.

Specification of Letters Patent.

Patented Aug. 10, 1915..

Application led January 29,1914. y Serial No. 815,220.

To all whom t may concern Be it known that I, RICHARD V. BARRY, citizen of the United States, residing at 0ttumwa, in the county of lVapello and State of Iowa, have invented new and useful Improvements in Grain-Shocking Attachments for arvesting-Machines, of which the following is a specification.

My present invention pertains to grain shocking attachments for harvesting machines; and it contemplates the provision of a simple, compact and reliable construction, adapted to receive bundles of grain fi'oin the bundle-binding mechanism of a grain harvester, and bind the bundles into a shock, and stand the shock on end on the ground at the side of the machine.

The invention in all of'its details will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specificatin, in which:

Figure l is a top plan view illustrating the application of the attachment constituting the preferred embodiment of my invention as applied to a conventional harvesting machine. Fig. 2 is an enlarged detail plan view of the mechanism for establishing and disconnecting the coupling of the packer shaft of the organized bundle binding mechanism with the shock binding mechanism.

Fig. 3 is a detail view illustrative of the mechanism for transmitting motion from the needle shaft 23a of the bundle binding mechanism to the sleeve 1l. Fig. 4 is a 4top plan view of the clutch member that is adapted to rotate with thel cradle shaft 2. Fig. 5 is a section taken transversely through said shaft and showing said clutch member in end elevation. Fig. 6 is a fragmentary view illustrating the organized bundle binding mechanism of the harvesting machine. Fig. 7 is an enlarged detail'plan illustrative of the means for holding the cradle shaft 2 against rotation.- Fig. 8 is a -viewshowing in side elevation the disk comprised in said means. Figs. 9, 10 and 1l are detail views showing in side elevation the cradle and the butt lingers in the dierent positions they assume.

Similar letters and numerals of reference designate corresponding parts in all of the .views of the drawings.

The main frame A of the harvester is sup p orted by a ground wheel B, in the conventional manner, and is equipped with the usual appurtenances of a grain harvester such as the deck-board C, the needle D, the packer E, the knotter F and the breastplate G. These parts constitute an organized bundle-binding mechanism, and I would here have it understood that the bundlebinding .mechanism forms no part of my present invention, and that, therefore, it may be of the construction illustrated or of any other construction compatible with my grain-shocking attachment invention without involving departure from the scope of the same as claimed.

In furtheranceof my present invention, a sub-frame l is fixed with respect to the harvester frame A, and in the said frame l is ]ournaled the shaft 2 of a cradle 3 that is adapted to receive bundles of grain and hold the same while they are being bound into a shock, and is also adapted to deposit the shockon end on the ground at the side of the path of the machine during the travel thereof.

Fixed with respect to the wheel B is a sprocket gear 5 having twelve teeth, and loosely mounted on the cradle shaft 2 is a sprocket gear'; the said gear 6 being provided with eight teeth, and being connected with the gear 5 'through 'the medium of a sprocket belt 7.

8 is the shaft of the packers comprised in the bundle-'binding mechanism of the harvesting machine. Fixed with respect to the shaft 8 is a sprocket gear 9 through the medium of which the packer shaft is rotated in the ordinary well-known manner. Also fixed on the shaft 8 is a sleeve 10 that extends through the hub of the gear 9L On said sleeve 10 is loosely mounted a sleeve 11, the inner end portion 11a kof which is angular in cross-section. Fastenedby aset-screw or other suitable means to the sleeve 11 is a beveled gear 12. Intermeshed with said gear l2 is a beveled gear signed to operate the binding and knotting 13 on a shaft 14, de-

mechanism of the shocker. 1t will here be understood that the packer shaft is rotated continuously during the operation of the machine. The sleeve 11, however, is rotated only when it is set in motion by the gear 15. This gear is designed to slide on and turn with the angular end portion of the sleeve 11, and is provided at one side with clutch teeth 1G and a beveled projection 17. Then the gear 15 is moved inwardly, its teeth 1G are engaged with the complementary teeth of a clutch member 18 that is fixed to the packer shaft. The gear 15 is moved inwardly through the medium of the mechanism best shown in Fig. 2. This mechanism comprises a sleeve 19 movable endwise on and rotatable about the sleeve 11, a ratchet disk 20 fixed on said sleeve 19, a radial projection 21 (preferably inthe form of an anti-friction roller as shown), carried by the sleeve 19, a crank arm 22 fixed on the shaft 23a of the bundle needle D, a pawl 23 pivoted to the arm 22 and arranged to engage the teeth of the ratchet disk 20, which teeth are preferably eight in number, and an inclined cam 24 fixed to a portion of the frame 1 and adapted at a certain time to engage the projection 21 and thereby move the gear 15 laterally inward and into engagement with the clutch member 18 that is fast on the continuouslyT rotating shaft 8. The operation of this portion of my novel mechanism is as follows: As each bundle of grain is bound, the pawl 23 coperating with the teeth of the ratchet disk 2O on the sleeve 19 turns the said sleeve through a part of a revolution. This continues until the projection 21 engages the inclined cam 24, when the gear 15 is engaged with the cam member 18, whereupon the sleeve 11 will be caused to rotate with the shaft 8, and the shaft 14 will also be caused to rotate, and through the medium of the latter the binding and shock` ing mechanism of the shocker will be actuated, as hereinafter set forth. Three revolutions of the packer shaft 8 and gear 15 are required to bind a shock collected in the cradle 3, and then a rod 25, guided at 26 on the frame 1 is pushed into the position shown by full lines in Fig. 2, so as to engage the beveled projection 17 at the proper time, and thereby move the gear 15 out of engage ment with the clutch member 18 and stop the binding and knotting mechanism of the shocker. The rod is connected to a crank arm 27 on the needle shaft 28 of the shocking mechanism; the shocking needle being numbered 29. On the upward movement of the said needle 29 to bind, the rod 25 is drawn rearwardly to the position shown by dotted lines in Fig. 2. Then on the downward movement of the needle 29 the rod 25 is moved to the position shown by full lines in F ig. 2, with the result that when the projection 17 engages the rody 25, the gear 15 will be disengaged from the clutch member 18, and the operation of the binding and knotting mechanism of the shocker will be suspended, this in order to permit of the collection of the requisite number of bundles toform a shock in the cradle 3.

30, Fig. 2, is a right-angle linger connected with the arm 22 on the shaft 23a and designed to engage a peripheral projection 31 on the gear 15. Zhen the first bundle that is to be comprised in a shock is being bound, the finger engages the peripheral projection 31, and thereby moves the gear 15 through a part of a revolution, and in that way moves the projection 17 past the rod 25.

Fixe-d to and movable with the needle 29 of the binding and knotting mechanism of the shocker is a rod 39. This rod serves irst-to unlock the cradle shaft 2, and then to bring about the rotation of the same. |The cradle shaft 2 and the cradle 3 are held against rotation while the bundles to form a shock are being deposited in the cradle through the medium of a disk fixed on the shaft 2 and having beveled lugs 41, 41LL 4.

at its opposite sides, a pivoted latch 411, and a lever 42 having a lug 43; said lever and latch being connected by an interposed retractile spring 41C.

the cradle 3 in horizontal position while the shock is being gathered in the cradle. The latch 41b prevents backward movement of cradle 3. 1t assumes a position back of the lug 41 at each revolution of the cradle shaft and cradle. The lever 42 is provided at one end with an eye 45 adapted for the engagement of an abutment 46 on the rod 39, and hence it will be manifest that on the upward stroke of the needle 29 the shaft 2 and cradle 3 will be rendered free to be turned. linmediately after the unlocking of the shaft 2 and cradle 3, as stated, the shaft 2 is oonnected with the sprocket gear 6, whereupon the shaft and cradle will be rotated to discharge the bound shock and stand the same on end on the ground. The said connection is effected through the medium of a lever 60, fulcrumed at one end and having an eye 61 at its opposite end opposed to an abutment 32 on the rod 39, and a clutch member G3 opposed to clutch teeth 64 on the sprocket `geen 3, and mounted to slide on and turn with the cradle shaft 2. The lever (SO has a portion that loosely receives the cradle shaft 2, and is arranged against the outer side of the clutch member 63, and hence it will be seen that movement of the lever by the rod 39 will be attended by movement of the clutch member 63 into engagment with the clutch teeth 64. On the subsequent rotation of the clutch member G3 with the cradle shaft 2 and the cradle 3, the inclined portion 65 of the clutch member 63 will, by co.-

operating with a stationary anti-friction L The lug 43 of lever 42 engages the lug 41El of disk 40 and holds ill-49,492

roller 66 draw the clutch member63 .out of engagement with the clutch teeth 64, this at the completion of the revolution of the shaft 2 and cradle 3, at which time the latch 41b will assume a position back of lug 41 on the disk '40 to lock said shaft and cradle.`

` Fixed on the outer end of the shaft 14 is a beveled gear 70. This gear 70 is intermeshed with a beveled gear 71 von a shaft 72, and the said gear 71 is connected through a pitman 7 3 with a crank 74 on theneedle shaft 2S to actuate the latter. Ink addition to thegear 71, the shaft 7 2 is equipped with a knotter gear 73a which per se is of the ordinary construction. 1t will also be observed that supported on a frame bar 74 and arranged opposite the knetter gear 73a is a conventional breast plate through which the needle is designed toproject.

rlhe means for transmitting motion to the sprocket gear 9 with a view to rotating the packer shaft of the organized bundle-binding mechanism forms no part of my invention, and I have therefore deemed it unnecessary to illustrate said means. y

As will be gathered from the foregoing, when a shock which may comprise any suitable number of bundles is gathered in the cradle 3, the shock-binding mechanism 'is automatically put into operation; the shock being bound around the top with a view to assuring the shock being stood on its base when it is set off by'the cradle 3. It will also be gathered that Vthe cradle 3 is automatically unlocked and caused to rotate to set the shock on its base; the said cradle revolving over the discharged shock and back into place to receive another shock.

lfith a view to contributing to the proper `placing of the shocks on the ground during the forward travel of the machine, 1 provide the mechanismshown in Figs. 1, 9, 1() and 11. The said mechanism comprises an eccentric 80 fixed on the cradle shaft 2, an eccentric-strap 81 mounted on said eccentric, a transverse shaft 82 journaled in bearings on the forward portion ofr the subframe 1 and having an angularly-disposed arm 83 at its outer end and also having a crank 84, a bar 85 reaching laterally outward from'the arm 83 and carrying a plurality of fingers S6 adapted to be moved to and from a position in front of and at right angles to the cradle 8, when the latter is in its receptive position, and a rod 87 interposed between and connecting the eccentric strap S1 and the crank 84.l The movements of the said parts are so timed that the fingers 8G rest in an upright position at the butts of the bundles while the shock is being formed, and incidental to the delivery of the shock the rotation of the eccentric 80' through the mechanism described will lower the fingers to a horizontal position, thereby enabling the lingers to support the shock and preclude the same being thrown forward by the momentum of themachine.
